Also included is our 100 Micron filtration bag on all AETech sump models.

One of the best designed refugium section available in a sump.

Full four black baffle design with our positive flow refugium section. This forces water from below the surface of the refugium compartment to empty into the return compartments surface section, giving the maximum oxygenation and circulation to the water in all compartments. This designed circulation of water makes for the best refugium section, allowing algae and plankton to prosper in nutrient rich water.
